Statistics help

Hey guysI need to compare two different samples to check if they are providing the same answers.Basically I have a set of results from two different programs, and what to check if the results are the same.The null hypothesis would be that both programs give the same results.

Yet unfortunately the more i read the more i get confusedDo you know which technique it is ideal to use.I have brought it down to t-test and ANOVA yet i really don't know what is the difference between them.
